USB technology is great, and now USB 2 technology is forty times faster. USB Universal Serial Vehicle (English, Universal Serial Bus) standard is a hardware driver that allows users to plug a peripheral device to a USB port, configure itself and it is ready for use. It is one of the last big hits in the history of computing. Not only because it works well, but because it makes life easier for the average user.

A port is not just for external devices, also controls the transfer of reason and the reason that information can be transferred between a computer and an external component.
This is where the USB port shows its splendor. On average, a USB port allows data to travel ten times faster than a parallel port. It is also much faster than a parallel port.

Anything can be plugged into a USB port, keyboards, cameras, microphones, joysticks, modems, disk drives, printers and scanners. You can even buy a good USB speakers to enjoy the best digital sound quality on your computer.

USB MEMORY

the USB memory is a mass storage device that uses flash memory to store information that may be required. It connects via a USB port and the information that you enter this may be modified millions of times over its lifetime.

J-Utilities

USB drives are common among people who carry data from home to workplace and vice versa. Theoretically they can retain data for 20 years and written up a million times.
Although they were initially designed to store data and documents, it is common to find in the USB memory programs or files of any type because they behave like any other file system.

J-DPrimary components

The typical parts of a USB memory are:

A male USB connector type A (1): Provides the physical interface with the computer.
USB mass storage driver (2): Implement the USB controller and interface provides uniform and linear for serial USB devices designed to block, while hiding the complexity of the orientation blocks,J removing blocks and balance of wear. This driver has a small RISC microprocessor and a small number of circuits of RAM and ROM.
NAND Flash memory circuit (4): Stores data.Crystal oscillator (5): Produces the master clock signal at 12 MHz device and controls the flow of data through a phase locked loop (phase-locked loop)
